Evolution bed

ABSTRACT

The Evolution Bed is a specially designed hospital mattress, with the surface of the mattress boasting a series of inflatable air bladders which are programmed to periodically release, thus alleviating pressure to various points of the body. The Evolution Bed is offered in a wide variety of comfort choices from soft pillow top versions to extra firm, back supporting models. This mattress is manufactured of durable foam material and covered in all-cotton batting, and in another embodiment, produced as an innerspring mattress containing a series of stainless steel coils which are covered in dual insulators and fiber padding and secured in place via durable steel border rods. The novel feature of the Evolution Bed is found in the inclusion of a system of air bladders which encompass the top of the mattress. Configured in a series of undulating rows which run horizontally across the surface of the mattress, these air bladders are inflated and released via an internal motor which disperses air through the individual bladders at timed intervals allowing the individual sections of the mattress expand and contract, thus serving to vastly reduce pressure to specific areas of the body.

CLAIM OF PRIORITY

This patent application claims priority under 35 USC 119 (e) (1) fromU.S. Provisional Patent Application Ser. No. 61/397,964 filed Jun. 18,2010, of common inventorship herewith entitled, “Evolution Bed.”

FIELD OF THE INVENTION

The present invention pertains to the field of air bed devices, and morespecifically to the field of multi-chambered air bed devices withautomatic pressure variation capability.

BACKGROUND OF THE INVENTION

The prior art has put forth several designs for multi-chambered air beddevices with automatic pressure variation. Among these are:

U.S. Pat. No. 4,394,784 to Gerald R. Swenson, et al describes a bed ormattress structure having at least one pneumatic bladder confined withinan outer perimeter of resilient but relatively firm edging material,wherein air flow tubes are coupled into the pneumatic bladder and areconnected to an electrically driven blower assembly being controllableby at least one hand held control unit.

U.S. Pat. No. 6,266,833 to Joenne Lin describes an air bed structurecapable of alternate aerating and lying thereon on one's side, wherein,the air bed is divided into a right and left part each being comprisedof a plurality of elongate air bladders in several sets or groups.

U.S. Pat. No. 6,695,798 to Chi-An Chang describes an air cushion bedwhich includes a massaging device comprising an air cushion, vibratingmotor, motor casing, massaging plate and adhesive strip. The air cushionbed utilizes a microcomputer to activate the vibrating motor so that apatient resting on the massaging device can be massaged on the backportion through the vibration of the massaging plate.

None of these prior art references describe the present invention.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a multi-chamberedair bed device with automatic pressure variation.

DETAILED DESCRIPTION OF THE INVENTION

Millions of people visit doctors' offices, clinics and hospitals everyyear. For those who must undergo surgical procedures or embark on anovernight or extended hospital stay, the patient is typically assigned ahospital bed on which to recuperate and rest during their time in thehospital. Usually boasting various settings with which to raise the heador foot of the bed, these beds are designed with patient comfort in mindand are a crucial element in any patient ward or room. For thosepatients who suffer serious illness, paralysis or other types of limitedmobility brought on by medical conditions or age, the vast majority oftime is spent confined to a bed.

Unfortunately, because the vast majority of a day is spent in a oneposition, patients confined to continual bed rest are at serious risk ofdeveloping bed sores. Bedsores, more properly known as pressure ulcersor “decubitus” ulcers are painful lesions caused by many factors such asunrelieved pressure, friction, humidity, temperature, age, continenceand medication. While bed sores can occur on any part of the body, theselesions are particularly prevalent over bony or cartilaginous areas suchas the sacrum, elbows, knees and ankles. Although preventable andcompletely treatable if found early, bedsores can lead to dangerousinfections and are often fatal, even under the auspices of medical care.

The present invention, hereinafter referred as the Evolution Bed,provides a practical way of preventing bed sores from developing inbedridden patients. Simply stated, the Evolution Bed is a speciallydesigned hospital mattress, with the surface of the mattress boasting aseries of inflatable air bladders which are programmed to periodicallyrelease, thus alleviating pressure to various points of the body.Similar in function to a traditional hospital mattress, the EvolutionBed is offered in a wide variety of comfort choices from soft pillow topversions to extra firm, back supporting models. This mattress ismanufactured of durable foam material and covered in all-cotton batting,and in another embodiment, produced as an innerspring mattresscontaining a series of stainless steel coils which are covered in dualinsulators and fiber padding and secured in place via durable steelborder rods. The novel feature of the Evolution Bed is the inclusion ofa system of air bladders which encompass the top of the mattress.Configured in a series of undulating rows which run horizontally acrossthe surface of the mattress, these air bladders are inflated andreleased via an internal motor which disperses air through theindividual bladders at timed intervals allowing the individual sectionsof the mattress expand and contract, thus serving to vastly reducepressure to specific areas of the body, in turn greatly reducing therisk of bed sores.

The Evolution Bed is a practical product invention which offersconsumers a number of significant benefits and advantages. Foremost, theEvolution Bed provides medical professionals a practical way in which toprevent bed sores from occurring in bedridden patients. A speciallydesigned mattress featuring a series of inflatable air bladders whichserve to alleviate pressure to specific points of the body, theEvolution Bed reduces the strain and stress placed on bony orcartilaginous areas that occur as a result of long hours spent bedbound. With air periodically released from the bladders, pressure tospecific points of the body is reduced, in turn preventing pressuresores from occurring in the first place. With painful bedsoreseffectively eliminated, the dangerous associated infections are alsoeradicated, thus resulting in a healthier and happier patient.Eliminating the need to continuously turn and reposition the patient,simply in order to alleviate pressure points, the Evolution Bed is apractical product which enables caregivers to focus on other, moreimportant aspects of care. Bed bound patients especially appreciate theEvolution Bed. Extremely comfortable, this unique mattress providesoptimal support during long hours confined to a bed. Ideal for use inhospitals, nursing homes and other long term care facilities, theEvolution Bed also prove an invaluable commodity to those who depend onhome health care services. Durably constructed, the Evolution Bedwithstands years of use, with ease.

The Evolution Bed is a unique product invention which offers medicalcare providers a simple means of reducing the risk of bed sores in bedbound patients. Ergonomic in design, this unique mattress is supremelycomfortable to use. Reasonably priced, the Evolution Bed is wellreceived by health care professionals and their patients.
